| The rate of soil respiration to varying stand ages was studied in four Robinia pseudoacacia stands(18-, 23-, 28- and 35-year old) throughout one year from September 1998 to August 1999. Soil temperatures showed a pronounced seasonal pattern, in contrast to soil moisture. The highest rate of soil respiration was generally found in August when soil temperatures were the highest, and the lowest in January. The daily rate of soil respiration amounted to 5.51($g;CO_2{cdot}m^{-2}{cdot}day^{-1}$) for 18-year old stand, 5.28 for 23-year old stand, 8.29 for 28-year stand, and 2.67 for 35-year old black locust stand, respectively. The $Q_{10}$ values were ranged between 1.63 and 1.66, averaging 1.65 for the R. pseudoaca'cia stands. The results indicate significant correlation between soil temperature and soil respiration for all four stands(r=0.96 to 0.97). Among the study stands, the annual rate of soil respiration was the highest ($3.03kg;CO_2{cdot}m^{-2}{cdot}yr^{-1}$) for 28-year old stand. |
